Friendship is always a sweet responsibility, never an opportunity.

If you have one true friend you have more than your share.

A true friend never gets in your way unless you happen to be going down.

There are no rules for friendship. It must be left to itself. We cannot force it any more than love.

Friendship is unnecessary, like philosophy, like art... It has no survival value rather it is one of those things that give value to survival.

Silences make the real conversations between friends. Not the saying but the never needing to say is what counts.

Friendship is the shadow of the evening, which increases with the setting sun of life.

A quarrel between friends, when made up, adds a new tie to friendship.

Friendship is certainly the finest balm for the pangs of disappointed love.

Caring for but never trying to own may be a further way to define friendship.
